There are discrete codes available www.olevia.com/rs232/rs232.aspx I have the 232So in theory this Tv should be able to be integrated into LinuxMCe right??

So here are my questions.

1. Cable - db9 serial to min d9in8 - strait thru or null modem ??2. Is there a template for one of the supported TV's that can be modified with Olevia codes. If so where and how can I edit it.3. Proper mode line to get 1360x768 @60hz right now 1280x720 (Does not fill screen)

Maybe you want to look at the template for "Plasma RS232" (AV Equipment). It should give you a basic understanding how a TV device should like. Adding a new template for a rs232 controllable device is easy (see the Marantz page in the wiki). Don't forget to add "Live TV" as embedded device.
